Hi, am hoping some here could shed some light on this problem.
About a month ago, I pulled up at a store, came out 10 minutes later to a no start - click only, no crank. Battery is good, I thought, but it started with a boost.
Took it to a well-regarded shop, it started fine for them multiple times - they never saw a no start issue, but they replaced my old alternator, claiming it had failed the diode test with their AVR tester.
NINE DAYS go by - all good
Then ... started car in garage - much more noise under hood! Key off, engine stops, but starter keeps cranking! Checking the power distribution center, I see all the relays are same part number - so I swap out the possibly suspect starter motor relay for another.
NINETEEN DAYS go by - all good
Then, this weekend, back to first symptom: key on to start, click only, no crank. Tried it multiple times - can't get it started.
Other issue noted - one engine ground strap is no longer connected to firewall. Power windows don't work (just prior to these starter issues) - possible broken wiring in driver's door pass thru (I've previously seen & repaired similar issue with trunk remote release wiring)
SO...
Is the problem the starter, or the ignition starter switch? Very curious how the starter can continue to get power to activate, and try to crank when the key is in the off position.
No other apparent abnormalities observed in the dash lights / accessory operation.
Code scan via key rock back & forth method - P0302 cyl 2 misfire (its been doing that a while), and P1684 - TCM disconnected from battery power B+ or ground. My neighbour has a OBDII reader - it only reads P0302.
Engine is the 3.2L
